Abstract

trata-se de sistemas de controle de velocidade de enlace para otimização de energia. em um aspecto, um enlace de comunicação ajusta uma velocidade de transferência de dados com base em níveis de utilização de enlace. em um segundo aspecto exemplificativo, uma ou mais condições que afetam uma velocidade de enlace são ponderadas e coletivamente avaliadas para determinar uma velocidade de enlace ideal ou eficiente. ajustando-se a velocidade de enlace dessa maneira, velocidades de enlace mais baixas podem ser usadas, e economias de energia útil podem ser efetuadas.These are link speed control systems for energy optimization. In one aspect, a communication link adjusts a data transfer rate based on link utilization levels. In a second exemplary aspect, one or more conditions affecting a link speed are weighted and collectively evaluated to determine an optimal or efficient link speed. By adjusting the link speed in this way, lower link speeds can be used, and useful energy savings can be realized.
